Insert script into header in Next.js using Script component

<p>I want to insert tracking code from an application called Zoho in the Head section of every page of my Next.js application. I'm using a file called _document.tsx and it works fine. For a skewed script, Next.js recommends using the Next.js Script component (https://nextjs.org/docs/messages/no-script-tags-in-head-component). I followed the instructions and inserted the script into brackets, but it was ignored without an error message.Can I enter this code in the Head section of the _document.tsx file? Would it be better to split it into a separate component?</p> <p>任何建议都将有所帮助</p> <pre class="brush:php;toolbar:false;">import Document, { Html, Head, Main, NextScript, DocumentContext, DocumentInitialProps, } from "next/document"; import Script from "next/script"; class MyDocument extends Document { static async getInitialProps( ctx: DocumentContext ): Promise<DocumentInitialProps> { const initialProps = await Document.getInitialProps(ctx); return { ...initialProps }; } render() { return ( <Html lang="en"> <Head> <meta charSet="utf-8" /> <link href="https://fonts.googleapis.com/css?family=PT Sans&display=optional" rel="stylesheet" /> <meta name="msapplication-TileColor" content="#596285" /> <meta name="msapplication-config" content="/favicon/browserconfig.xml" /> <meta name="theme-color" content="#ffffff" /> {/* for Zoho Marketing Automation */} <Script id="zoho-ma"> {`var w = window; var p = w.location.protocol; if (p.indexOf("http") < 0) { p = "http" ":"; } var d = document; var f = d.getElementsByTagName("script")[0], s = d.createElement("script"); s.type = "text/javascript"; s.async = false; if (s.readyState) { s.onreadystatechange = function () { if (s.readyState == "loaded" || s.readyState == "complete") { s.onreadystatechange = null; try { loadwaprops( "myid#", "myid#", "myid#", "myid#", "0.0" ); } catch (e) {} } }; } else { s.onload = function () { try { loadwaprops( "myid#", "myid#", "myid#", "myid#", "0.0" ); } catch (e) {} }; }s.src = p "//ma.zoho.com/hub/js/WebsiteAutomation.js"; f.parentNode.insertBefore(s, f);`} </Script> {/* end Zoho marketing automation */} </Head> <body> <Main /> <NextScript /> <div id="notifications"></div> </body> </Html> ); } } export default MyDocument;</pre>

    I re-read the previous postNext 11 and adding Script tags not working. No scripts are rendered enter link description here and realized you can't put < Script> component is placed in the Head tag. Also, it should not be in _document.tsx but in _app.tsx (unless you use beforeInteractive, see link above).

    Because I also wanted to include the Google Analytics script, I created a component called TrackingCode as a separate js file. 

    import Script from "next/script";

function TrackingCode() {
  return (
   <>
  {/* Global site tag (gtag.js) - Google Analytics */}
  <Script src="https://www.googletagmanager.com/gtag/js?id=G-GOOGLEID" />
  <Script id="google-analytics" strategy="afterInteractive">
    {`
  window.dataLayer = window.dataLayer || [];
  function gtag(){window.dataLayer.push(arguments);}
  gtag('js', new Date());

  gtag('config', 'G-GOOGLEID');
  `}
  </Script>

  {/* for Zoho Marketing Automation */}

  <Script id="zoho-ma">
    {`var w = window;
var p = w.location.protocol;
if (p.indexOf("http") < 0) {
  p = "http" + ":";
}
var d = document;
var f = d.getElementsByTagName("script")[0],
  s = d.createElement("script");
s.type = "text/javascript";
s.async = false;
if (s.readyState) {
  s.onreadystatechange = function () {
    if (s.readyState == "loaded" || s.readyState == "complete") {
      s.onreadystatechange = null;
      try {
        loadwaprops(
          "mycode",
          "mycode",
          "mycode",
          "mycode",
          "0.0"
        );
      } catch (e) {}
    }
  };
} else {
  s.onload = function () {
    try {
      loadwaprops(
        "mycode",
        "mycode",
        "mycode",
         "mycode",
        "0.0"
      );
    } catch (e) {}
  };
}
s.src = p + "//ma.zoho.com/hub/js/WebsiteAutomation.js";
f.parentNode.insertBefore(s, f);`}
  </Script>
  {/* end Zoho marketing automation */}
</>
 );
}

export default TrackingCode;

    My _app.tsx file is as follows: 

    import "../assets/scss/material-kit.scss";
import "../node_modules/bootstrap/scss/bootstrap.scss";
import "../styles/globals.scss";
import { useEffect } from "react";
import type { ReactElement, ReactNode } from "react";
import type { NextPage } from "next";
import type { AppProps } from "next/app";
import TrackingCode from "../components/tracking-code";

import store from "../app/store";


export type NextPageWithLayout = NextPage & {
  getLayout?: (page: ReactElement) => ReactNode;
};

type AppPropsWithLayout = AppProps & {
  Component: NextPageWithLayout;
};

export default function MyApp({ Component, pageProps }: AppPropsWithLayout) 
{
 const getLayout = Component.getLayout ?? ((page) => page);
  useEffect(() => {
   typeof document !== undefined
      ? require("../node_modules/bootstrap/dist/js/bootstrap")
     : null;
  }, []);

return getLayout(
   <>
     <TrackingCode />
     <Component {...pageProps} />
   </>
  );
}
